The condensed structural formula for hex-3-ene is #"CH"_3"CH"_2"CH=CHCH"_2"CH"_3#.

The stem name –hex- tells us that we have a chain of six carbon atoms.

#"C-C-C-C-C-C"#

The -ene tells us that we have a #"C=C"# double bond and the -3- tells us that it is between C-3 and C-4.

#"C-C-C=C-C-C"#

Since there are no other substituents, we fill up the unused valences of #"C"# with hydrogen atoms to get a condensed structural formula.

#"CH"_3"-CH"_2"-CH=CH-CH"_2"-CH"_3#

Single bonds are often omitted in condensed structural formulas, so another acceptable answer would be

#"CH"_3"CH"_2"CH=CHCH"_2"CH"_3#
